A telephone pole has three cables pulling as shown from above, with F₁ = (300.0 N, 500.0 N), F2 = (-200.0 N, 0.000 N), and F3 = (0.000 N, -800.0 N). Find the magnitude and direction of this net force.

An antelope is being pulled by two forces whose vector-component expressions are: F1 = -3.5Ni + 3.4Nj + 3.9Nk F2 = 3Ni + 2.6Nj + -1.5Nk What is the angle (in degrees) between these two vectors?

Sue and Jenny kick a soccer ball at exactly the same time. Sue’s foot exerts a force of 57.5 N to the north. Jenny’s foot exerts a force of 109.5 N to the east. What is the direction of the resultant force (measured from East)? Answer in units of ◦ .

Four forces act on an object, given by  A = 49.3 N east,   B = 50.3 N north,   C = 76.7 N west,  and  D = 80.7 N south.  (Assume east and north are directed along the +x-axis and +y-axis, respectively.)   (a) What is the magnitude of the net force (in N) on the object? __________  N (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)  ___________ ° counterclockwise from the +x-axis

Three forces are applied to an object, as shown in the figure. Force ->F1 has amagnitude of 24.4 newtons (24.4 N) and is directed 30.0 degrees to the left of the (+) yaxis. Force ->F2 has a magnitude of 15.4 N and points along the (+) x axis. What mustbe the (a) magnitude and (b) direction (specified by the angle (theta) in the drawing) ofthe third force ->F3 such that the vector sum of the three forces is 0 N?

最 属国国 庫 庫 ! 国 庫 As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F, of magnitude 6.80 units acts on a box at the origin in a direction 6 = 29.0° above the positive x-axis. A second force F, of magnitude 5.00 units acts on the box in the direction of the positive y-axis. Find graphically the magnitude and direction (in degrees counterclockwise from the +x-axis) of the resultant force F, +F 2" 1 magnitude units direction counterclockwise from the +x-axis

Two workers are trying to move a heavy crate. One pushes on the crate with a force A, which has a magnitude of 480 newtons and is directed due west. The other pushes with a force B, which has a magnitude of 325 newtons and is directed due north. What is the magnitude of the resultant force A + B applied to the crate? Specify your answer up to one decimal place. Do not include units.

A force F1 of magnitude 6.30 units acts on an object at the origin in a direction θ = 47.0° above the positive x-axis. (See the figure below.) A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude and direction of the resultant force F1 + F2.

Four forces act on an object, given by  A = 40.3 N east,  B = 43.3 N north, C = 74.7 N west, D = 78.7 N south.  (Assume east and north are directed along the +x-axis and +y-axis,respectively.) (a) What is the magnitude of the net force (in N) on the object?   (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)

A force  F1  of magnitude 4.80 units acts at the origin in a direction 37.0° above the positive x axis.
